Slip-on cigarette tip



Nov. 30, 1954 A. E. WARNBERG SLIP-ON CIGARETTE TIP Filed April 18, 1951ATTORNEYS United States Patent O SLIP-N CIGARETTE TIP Archie E.Warnberg, Oklahoma City, Okla. Application April 18, 1951, Serial No.221,555 1 Claim. (Cl. 13110) This invention relates to a cigarette tip.

An object of this invention is to provide a tip for cigarettes, cigarsor the like which is of the disposable type, being formed of paperarranged as a tube which can be easily slipped onto an end of thecigarette.

A further object of this invention is to provide a tubular cigarette tiphaving a filter element therein which will filter the smoke and willalso provide body to the holder to hold the same against collapsing.

A further object of this invention is to provide a tip which may beimpregnated with a medicament, flavor or contain a filter which may beimpregnated or coated with perfume, flavor, medicament or contain anaromatic element of medical or perfume nature. The tip herein disclosedmay be used alone as an inhalent or inhaler of a disposable type.

A further object of the invention is to provide a filter tip of thischaracter having elements disposed therein tending to resist crushing ofthe tip upon the exertion of excessive pressure by the fingers.

In one form of this invention the tip is formed from a paper or fibroussheet having secured to one face thereof a corrugated element which maybe impregnated with a medicament, flavor, or aromatic element, and acotton or fibrous filter is disposed forwardly of the corrugated memberfor filtering the smoke and tar which are drawn from the tobacco in thecigarette.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claim.

In the drawings:

Figure l is a plan view of a blank strip showing a series of the filterelements in strip form for separation along a scored or perforated line.

Figure 2 is a longitudinal section through the tip with one of thefilter elements in applied position on a cigarette.

Figure 3 is a transverse section taken on the line 3-3 of Figure 2.

Figure 4 is a fragmentary sectional View taken on the line 4-4 of Figure2.

Referring now to the drawings, inclusive, and, first, to Figure 2 thenumeral 18 designates generally a form of slip-on tip which is mountedon the rear end of a conventional cigarette 19. The tip 18 isconstructed in the form of a tubular member 20 formed from a strip whichis rolled into tubular form with the ends overlapping and adhesivelysecured together as indicated at 21. The tubular member 20 has disposedtherein a corrugated member 22 which terminates at its forward endrearwardly from the forward end of the tubular member 20, and thecorrugated member 22 forms channels 23 through which smoke is adapted tobe drawn. The corrugated member 22 is preferably formed of absorbentmaterial such as absorbent paper or the like and is preferablyimpregnated with a medicament, an inhalant, or other aromatic meanswhich is activated by the heat and the smoke passing through thechannels 22 and the central channel 24.

At the forward end of the corrugated member 22 a fibrous filter element25 is positioned, the filter element 25 being in the form of cottonfibers or the like which are rolled into substantially cylindrical formleaving a central opening 26 as shown in Figure 4. The rear or inner endof the cigarette 19 is adapted to abut against the filter member 25 asshown in Figure 8.

The tips hereinbefore described are adapted to be formed in strip formas shown in Figure l with the tips having the tubular member 20 in fiator strip form and perforations 27 cut through adjacent tips in orderthat a single tip may be torn from a series of connected tips and thenrolled into the configuration shown in Figures 2, 3, and 4. The filtermember 25 is adapted to remove any tar, nicotine, or moisture drawn withthe smoke from the tobacco in the cigarette 19, and the heat of thesmoke passing through the filter 25 will activate the ingredientscontained or impregnated in the corrugated member 22. The corrugationswithin the tube are so dimensioned and arranged that substantiallysemi-cylindrical, relatively large channels of equal cross sectionalarea are maintained in each quadrant of the cross-sectional area of thefilter with four arcuate webs of substantial length interconnecting thesides of the said channels; the said webs maintaining the relativeposition of the channels and contributing to the rigidity of the device.This corrugated member 22 will provide body to the rear of the tip sothat the tip will not readily collapse when inserted in the mouth. Thepositioning of the corrugations one in each quadrant of the tip, willassure the presence of channels through the tubular member 20 rearwardlyof the filter 25 so that the smoke may be drawn therethrough in theevent the rear of the tip should be compressed or substantiallycollapsed.

What is claimed is:

A slip-on cigarette tip comprising a tubular member of an insidediameter slightly in excess of the outside diameter of a cigarette, acorrugated element formed of a tube of corrugated paper substantiallyequal in diameter to the outside diameter of the cigarette having aplurality of spaced, straight parallel substantially semi-cylindricalrelatively large channels of equal cross sectional area and equallyspaced circumferentially within said member, each in a quadrant of thecross sectional area of said member, said tube having a plurality ofarcuate webs of substantial length inter-connecting the sides of saidchannels and being secured to the inner wall of said member to maintainthe relative position of said channels and to afford rigidity to thesaid tip, and said tube terminating at one end inwardly from one end ofsaid member, and a fibrous filter having a central aperture extendinglongitudinally thereof in said member abutting said corrugated elementand terminating short of said one end of said member, whereby said tipmay be slipped over the end of a cigarette with said filter in abuttingrelation with the end of said cigarette, and whereby a substantiallyequal draft will be obtained in each said quadrant.
